For some inexplicable reason, Apple has decided to disable Dashboard by default in macOS Mojave, which is nothing short of a parody. Fortunately, turning it back on is a simple matter. Here's how to restore Dashboard in all its splendor.
For those who do not know Dashboard, this is a collection of widgets that has been around since Mac OS X 10.4 Tiger has been on the market for many years. Dashboard allows you to select widgets that you can easily access without interfering with other applications, or having to launch applications to perform a simple task. Calculators, sticky notes, easy access to the weather, etc. were perfect uses for Dashboard. Think about how widgets work on iOS and you have the right idea.
We do not know why, but Apple left Dashboard to languish, disabling it completely in macOS Mojave. It's a shame because we often want to do a quick calculation, for example. Opening the calculator is not difficult, but you do not have to press a calculator.
The dashboard is useful if your workflow from previous versions of macOS relies on it. Here's how to get it back.
Activation of the dashboard on macOS Mojave
To get started, click on the Apple logo at the top of the screen and select "System Preferences".
Once the system preferences are open, click on "Mission Control".
Towards the middle of the window you will see an entry for Dashboard. Click on the drop-down menu and select "As Space" or "As Overlay" according to your preferences. To get that Mac feel, we suggest you choose "Overlay".
If you want to change the way you call Dashboard, click the "Show Dashboard" drop-down menu at the bottom of the window and select the keyboard shortcut you want to use. F12 is the default value.
That's all we can say about it. From now on, when you call Dashboard via the method you have chosen, you will be welcomed by very good widgets, eager to serve you.
